UNITED STATES WILLIAM G. DUNN, OF CLARINDA, IOWA.

MOTOR SUPPORT AND, THRUST MEMBER.

Application filed November 21, 1921,, Serial No. 516,849. Renewed August7, 1924.

To all whom it may concern:

Be it known that l, VV'ILLIAM G. DUNN, a citizen of the United States,residing at Clarinda, in the county of Page and State of Iowa, haveinvented certain new and useful Improvements in} Motor Supportsautomobile accessories and has for its prin cipal object, to provide anovel attachment; for Ford automobiles to receive the thrust of theusual radius rod and to assist in supporting the weight of the motor,there by taking a great deal of strain from the usual hangers which arecommonly attached to the fly-wheel casing of the motor to sup-- port therear end of the latter. While these hangers are sufliciently strong tosupport the weight of the motor, they are often broken when the radiusrod thrusts rear-- wardly upon the motor with unusual force and there isalso danger of injuring other parts of the motor when such an occurrencetakes place. 13y useof my invention, however, all thrust of the radiusrod is taken up by a rigid transverse bar secured to the chassis frameand to the rear end of the motor.

A further aim of the invention is to provide a thrust receiving memberfor the radius rod, provided with an upwardly extending projection forsnug reception in the usual ball socket formed in the lower side of themotor base, so as to brace the thrust member to some extent, althoughany appreciable amount of thrust is prevented from being transmitteddirectly to the motor, due to the rigid nature of the thrustreceivingmember and its rigid connection with the chassis frame.

Yet another object is to provide an attachment of the class set forthwhich may be quickly and easily applied to any Ford machine without thenecessity of making any alterations Whatever in the construction of thelatter.

Vith the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the descriptive matter beingsupplemented by the accompanying drawings:

Figure 1 is a perspective view of a Ford motor and adjacent parts of thechassis, showing the application of my invention.

Figure 2 is a perspective View of the attachment and its securing means.

Figure 8 is a detail vertical sectional view as indicated byline 3-8 ofFig. 1.

Figure f is a vertical transverse sectional view .as indicated by linell of Fig. 3.

In the drawings above briefly described, the numerals 1 designate theside bars of an ordinary Ford chassis frame, to which the usual hangers2 are secured for supporting the rear end of the motor 3, said hangersbeing attached to the fly Wheel casing 41 in the well known manner. Thelower side of the motor base is provided with the well knownhemispherical socket- 5 which usually receives the ball 6 on the rearend of the radius rod 7, but in adapting my invention to the machine,the cap 8 which previously held the ball 6 in the socket- 5, is removedand said cap is later used to mount the ball in another socket withwhich the invention is provided.

In the preferred form of construction which is herein described andillustrated, a centrally depressed metal bar 10 is provided to extendacross the chassis frame under the rear end of the motor 3, directly infront of the fly wheel housing 4;, the ends of said bar being providedwith horizontal portions 11 whose inner and outer ends may be offset tosome extent, longitudinally of the machine, if desired. In view of thefact that the portions 11 form rests for the rear end of the motor, Ihave hereinafter referred to these portions as rests. The outer ends ofthe rests 11 are adapted to underlie the side bars 1 of the chassisframe and to be secured thereto by any suitable means such as theU-bolts 12. In the present form of construction, it is necessarytoemploy suitable spac ing blocks 13 between the rests 11 and the sidebars 1, but it will be understood that the equivalents of these blocksmight well be formed directly on the rests. The inner portions of therests 11 underlie the usual flanges 14 on the front side of the flyWheel housing 4:, bolts 15 being passed through the usual openings ofsaid flanges and through bolt holes 16 formed in the rests. By securingthe bar 10 in place in this manner, it supports a great deal of theweight of the motor 3 and is mounted in a sufficiently rigid ployed tohold said ball in the socket.

manner to effectively resist all strain exerted by rearward thrusting ofthe radius rod 7, which rod I intend to connect with the bar 10 as abovesuggested.

In the preferred form of construction, all parts of the bar 10 areformed of cast metal as shown, the upper edge of sald bar bemg providedwith a forwardly extending flange 17 while its lower edge is equippedwith a rearwardly projecting flange 18. These flanges permit the bodyportion of the bar to be in the form of a rather light web, due to theirreinforcing effect, and I utilize the upper flange 17 in connecting theradius rod 7 with the bar. This upper flange is provided with ahemi-spherical projection 19 extending upwardly therefrom and adaptedfor, reception in the ball socket 5, while the lower side of said flangeis formed with a hemispherical socket 20 extending into the projection19 and adapted to receive the ball 6 of the radius rod 7, the cap 8being e1;-

11 this connection, attention is directed mor particularly to Fig. 4,from which it will be seen that the flange 17 is formed with openings 21through which the vertical bolts 22 extend from the motor base, saidbolts pass ing through the usual openings in the cap 8 and carrying thewell known springs 23 and nuts 24 on their lower ends.

The construction just described establishes an effective connectionbetween the motor base and the bar 10, which serves to brace themrelatively, but said bar is of sufficient rigidity to receive allrearward thrust of the radius rod without transmitting any undesirableamount thereof to the motor, Tthrough the instrumentality of theprojection 19.

' My invention may be advantageously marketed and may be quickly andeasily attached to automobiles without the necessity of taking them to agarage or other shop and when once installed, it will be seen that themotor and its hangers are relieved of the intense strain to which theyare commonly subjected. Attention may further be direct ed to the factthat the invention. establishes a very rigid connection between themotor and the frame which prevents undue vibration of the former andresultant loosening of the hanger arms, which later produces ratherserious transmission troubles.

As excellent results have been obtained from the details disclosed, theymay well be followed, but I wish it understood that within the scope ofthe invention as claimed, numerous minor changes may be made.

I claim:

1. A motor supporting and thrust receiv ing attachment for automobilescomprising a rigid depressed bar adapted to extend across a chassisframe under the rear end of the motor, means for rigidly securing saidbar to the chassis frame and to the motor to take strain from thehanger-sol the latter, and means for connecting the usual radius rod ofthe automobile to said bar instead of to the motor, thereby takingadditional strain from said hangers.

2. A thrust receiving member for aulomo bile radius rods having aprojection for reception in the usual radius rod ball socket; of theautomobile motor.

A thrust member comprising a bar adapted to extend across a chassisframe under the rear end of the motor, said bar having a projection forreception in the usual radius rod ball socket in the motor and beingitself provided with a socket for the radius rod ball, and means forsecuring the ends of said bar to the chassis frame.

4. A thrust member comprising a bar adapted to extend across a chassisframe under the rear end of the motor, said bar having a hemi-sphericalprojection formed on its upper side for reception in the usual radiusrod ball socket of the motor, said bar being provided with a dowmvardlyopening hemi-spherical socket; extending into said projection to receivethe radius rod ball, said last named socket being adapted for coactionwith the usual cap to hold the ball in place,

and means for securing said bar to the chassis frame.

In testimony whereof I have hereunto set my hand.

WILLIAM (l. DUNN.
